Stabiliser (conditioner)

Chlorine, which we use as a sanitiser in our pools, is very unstable.The
effects of the sun's UV rays and high temperatures reduces chlorine's
effectiveness and breaks it down into inactive components.

Stabiliser, or cyanuric acid, is a compound which protects the chlorine
from the negative effects of UV and heat. It not only ensures that our
pool remains clean and safe for the swimmers throughout the day, but it
also reduces the amount of chlorine we need to add in order to maintain
these levels of disinfection.

"According to research results, pools without
stabiliser lose about 90% of their total chlorine residual on a
sunny day in two or three hours. Pools treated
with 25 to 50 milligrams per litre of cyanuric acid, however, under the
same conditions, lose only 10 to 15 percent of their total chlorine."
(White et. al. , 1972)

Ideally, the stabiliser should be maintained at a level of about 50 ppm,
the acceptable limits being 40-80 ppm. If you use a stabilised chlorine
product, you will need to add very little, if any, stabiliser. To find
out how much cyanuric acid your pool requires to raise the level of stabiliser,
you can use our stabiliser
calculator.

If the stabiliser level is too high, try using a non-stabilised chlorine
product until the level falls to the recommended limits.
